Duplications of the alimentary tract are rare malformations. A case of a 2-year-old girl with an intestinal intussusception caused by a cystic duplication of the cecum is presented. This case report is justified by its clinical features and the difficult diagnosis, which was only confirmed during surgery. Ultrasonography had documented an abdominal mass(More)
OBJECTIVE To study the effects of extensive intestinal resection on growing rats, with regard to animal weight and histomorphometry of the remaining small intestine. METHODS Forty growing rats were allocated according to the extent of small intestine resection: 60%, 70%, 80%, or 90%. The animals were weighed every week and observed for 30 days. Following(More)
BACKGROUND Renal ischemia/reperfusion injury induced by hemorrhagic shock (HS) and subsequent fluid resuscitation is a common cause of acute renal failure. The objective of this study was to evaluate the effect of combining N-acetylcysteine (NAC) with fluid resuscitation on renal injury in rats that underwent HS. MATERIALS AND METHODS Two groups of male(More)
PURPOSE To assess the protective effect of glycine in an experimental model of Neonatal Necrotizing Enterocolitis (NEC). METHODS Fifty (50) neonatal Wistar rats, from a litter of six female rats and weighing 4 to 6 grams, were used. Five animals were cannibalized and the 45 remaining were distributed into three groups: the G1 normal control group (n=12);(More)
PURPOSE The authors describe a modified technique of primary transanal rectosigmoidectomy for Hirschsprung's disease (HD), using a Swenson like procedure to perform the anastomosis between the colon and the rectum, and the preliminary results from this in children. METHODS Twenty children, of whom, 90% were boys and 10% girls, 50% white and 50% nonwhite,(More)
PURPOSE The purpose of this study was to establish morphologically the best time of vascular occlusion to induce ischemic preconditioning (IPC) for rat small bowel undergoing ischemia and reperfusion injury. METHODS After approval by the Ethics Committee, 36 EPM-1 young adult Wistar rats from 300-350 g were distributed into 6 groups: sham (S); ischemia(More)
PURPOSE To compare the surgical conditions and complications and patient and surgeon satisfaction in cataract surgery by phacoemulsification under topical anesthesia (TA) versus sub-Tenon block (STB). METHODS Prospective randomized comparative blind study, without placebo control. Patient satisfaction evaluated by the Iowa Satisfaction with Anesthesia(More)
PURPOSE To study the pH monitoring over eight hours, analyzing variables such symptomatology and esophagogastroduodenoscopy, as well as the following pH monitoring parameters: number of reflux episodes, number of episodes longer than five minutes, length of reflux time during the eight hours, and the episode of longest duration, for the diagnosis of(More)
Asymmetrical conjoined twins or heteropagus twins are extremely rare. They are characterized by an incomplete component (parasite) that is normally smaller and dependent on the host (autosite). In cases of an epigastric heteropagus twin, the insertion occurs in the epigastrium. There are few reports of epigastric heteropagus twinning in the English-language(More)
Apple-peel atresia (or Type-IIIb intestinal atresia) is an unusual type of jejunoileal atresia. They present with jejunal atresia near the ligament of Treitz and a foreshortened small bowel. Many surgical options have been used, but the optimal method of repair remains unclear. We present a case of a newborn with apple-peel intestinal atresia managed by(More)
